Two French security advisers seized in Somalia will be tried under Sharia law, an official from their captors, the Islamic al-Shabab militia, says.
The unnamed spokesman said they would be tried for spying and "conspiracy against Islam".
The two, who were training government troops, were kidnapped by gunmen in a Mogadishu hotel on Tuesday and later handed over to al-Shabab insurgents.
Al-Shabab and its allies control much of southern Somalia.
The al-Shabab official said no date had been set for the trial of the two men.
They were on an official mission to train the forces of the interim government, which has recently appealed for foreign help to tackle Islamist insurgents.
Moderate Islamist President Sheikh Sharif Sheikh Ahmed was sworn in in January after UN-brokered peace talks.
He promised to introduce Sharia law but the hardliners accuse him of being a western stooge.
Somalia has not had a functioning national government since 1991.
